Abstract: The invention relates to an aqueous binder composition containing, relative to the total dry weight of the binder composition, 10 to 40% by weight of a hydrogenated sugar, 25 to 55% by weight of citric acid, 25 to 50% by weight of a polysaccharide, and 1 to 10%, preferably 2 to 6%, by weight, of sodium hypophosphite or hypophosphorous acid. The polysaccharide is dissolved in the aqueous binder composition and chosen from functionalized starches and dextrins having a weight-average molar mass of between 150,000 and 2,000,000 and a solubility in water of between 50 and 85%. The invention also relates to a method for manufacturing non-woven webs based on mineral or organic fibers using such a composition and the non-woven webs thus obtained.
